Each of the volumes of the Chemical Engineering Series includes numerical examples to
illustrate the application of the theory presented in the text. In addition, at the end of each
volume, there is a selection of problems which the reader is invited to solve in order to
consolidate his (or her) understanding of the principles and to gain a better appreciation
of the order of magnitude of the quantities involved.
Many readers who do not have ready access to assistance have expressed the desire for
solutions manuals to be available. This book, which is a successor to the old Volume 4,
is an attempt to satisfy this demand as far as the problems in Volume 1 are concerned.
It should be appreciated that most engineering problems do not have unique solutions,
and they can also often be solved using a variety of different approaches. If therefore the
reader arrives at a different answer from that in the book, it does not necessarily mean
that it is wrong.
This edition of the solutions manual relates to the sixth edition of Volume 1 and incorporates
many new problems. There may therefore be some mismatch with earlier editions
and, as the volumes are being continually revised, they can easily get out-of-step with
None of the authors claims to be infallible, and it is inevitable that errors will occur
from time to time. These will become apparent to readers who use the book. We have
been very grateful in the past to those who have pointed out mistakes which have then
been corrected in later editions. It is hoped that the present generation of readers will
prove to be equally helpful!
